Compact floribunda rose plant named ‘Poulcas058’

ABSTRACT

A new garden rose plant of the Compact Floribunda class which has abundant, orange red flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrid.

Variety denomination: ‘Poulcas058’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of roseplant which originated from a controlled crossing between the femaleseed parent, an unnamed seedling, and the male pollen parent, also anunnamed seedling. Both of the parent varieties are non-patented.

The two parents were crossed during the summer of 2008 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulcas058’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by the following characteristics. The malepollen parent plant has light red flowers while the new variety hasorange red flowers. The female seed parent plant has light pink flowerswhile the new variety has orange red flowers.

The objective of the hybridization of this rose variety was to create anew and distinct variety with unique qualities, such as:

-   -   1. Uniform and abundant orange red flowers;    -   2. Vigorous, but compact growth when propagated on its own        roots;    -   3. Exceptional disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulcas058’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2008 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulcas058’ was selected in thespring of 2009 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulcas058’ by rooted cuttings was first doneby Mogens N. Olesen in the nursery in Fredensborg, Denmark in July,2009. This initial and other subsequent asexual propagations conductedin controlled environments have demonstrated that the characteristics of‘Poulcas058’ are true to type and are transmitted from one generation tothe next.

DESCRIPTION OF THE DRAWING

The accompanying color illustrations show as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems, of‘Poulcas058’.

Specifically illustrated in FIG. 1 of the drawings are open flowers,flower buds upon opening on a branch, and petals detached revealing thereceptacle and reproductive flower parts.

Specifically illustrated in FIG. 2 of the drawings are leaves and stems.Plants shown are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulcas058’,as observed in its growthin a field nursery in Linn County, Oreg. Observed plants are 2 years ofage, and were grown on their own roots. Color references are made usingThe Royal Horticultural Society (London, England) Colour Chart, 2001,except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety‘Poulcas049’, U.S. Plant Pat. No. 28,229 are compared to ‘Poulcas058’ inChart 1.
